Abstract
The majority of developing nations still utilize landfills as their primary method of disposing of municipal solid waste (MSW), and Indonesia is no exception to this technology. On the other hand, landfill contributes a significant fraction of plastic in the global environmental leakage from mismanaged landfill and open dumping site in Asian countries. Furthermore, Indonesia has a long history of landfill mismanagement and open dumping. The loss of plastic to the environment could lead to multisectoral impacts on the health, environment, and economy. In this paper, we analyze the current situation of landfill and the potential of plastic waste leakage from landfills to the environment using systematic review and metadata analysis using GIS in Indonesia. In addition, this study analyses potential plastic leakage based on the distance to the waterways, leachate treatment facility and landfill facility. Based on the analysis, only around 11% of the landfill were claimed as sanitary landfill, yet only 3% operated based on the sanitary landfill standard of Indonesia after the analysis. The controlled landfill is also implemented in Indonesia at around 52%, and open dumping is around 37% of total final disposal. Based on the GIS analysis, more than 20% of landfill in Indonesia are near the waterways, which increase the potential for plastic leakage. Policymakers can use the resulting study to identify and prioritise ways to stop the environmental leakage of plastics from landfills.
